Signal Processing Type

Supports multiple types of signal inputs and outputs, typically including:

Analog signals: 4–20 mA current, 0–10 V voltage

Digital signals: switch-type inputs/outputs (DI/DO)

Certain channels are equipped with optoelectronic isolation (isolation voltage ≥ 1000 VDC), providing excellent anti-interference capability and ensuring stable operation in electrically noisy industrial environments.

Power Specification

The module is powered by the system motherboard, operating at a standard 24 VDC input.
It features low power consumption (typical value ≤ 5 W), helping to conserve system power resources and maintain overall energy efficiency.

Environmental Adaptability

Designed for reliable operation in harsh industrial conditions:

Operating temperature: 0°C to +60°C

Storage temperature: –40°C to +85°C

Relative humidity: 5%–95%, non-condensing

This ensures dependable performance under varying temperature and humidity conditions commonly found in process control environments.

Physical Design and Installation

Built in a compact board-card format, the module is designed for installation on ABB TU series base plates (e.g., TU515, TU516).
The dimensions are compatible with other modules in the same series, allowing for easy replacement, expansion, and modular system integration.

Core Functional Features

Signal Isolation and Conditioning

Utilizes optoelectronic or electromagnetic isolation technology to block interference between field equipment and controllers.
Input signals are filtered, linearized, and amplified to ensure high signal accuracy and reliability.

Flexible Configuration

Selected channels support software-based configuration.
Signal types (current/voltage), measurement ranges, or alarm thresholds can be set using ABB Control Builder software, allowing customization for diverse field device requirements.

Status Monitoring and Diagnostics

Equipped with onboard LED indicators for visual status feedback:

Power supply status

Signal transmission activity

Fault alerts (e.g., channel short circuit, signal overload)

These diagnostic indicators enable fast and convenient on-site troubleshooting and maintenance.

System Compatibility

Fully compatible with ABB AC 800M controllers and Freelance DCS systems.
No additional hardware adaptation is required — the module can be directly integrated into existing system communication buses such as PROFIBUS and EtherNet/IP.

Typical Application Scenarios

Industrial Process Control:
Used in applications such as chemical plants, metallurgical lines, and energy systems, where sensors measure parameters like pressure, temperature, or flow. The module converts field analog signals into standard, controller-recognizable signals.

Drive System Signal Processing:
Provides signal isolation and transmission for control commands (e.g., start/stop, speed reference) between field devices and ABB frequency converters (ACS series), preventing high-frequency interference from affecting the control system.
